徴とするロールシフト装置。 In a multi-stage rolling mill configured to allow rolls to be moved in the axial direction by a hydraulic cylinder, a pressure sensor detects the pressure generated in the hydraulic cylinder while the rolls are moving, and a pressure sensor detects the axial position of the rolls. A position detection device, the hydraulic cylinder, and a volume change in response to a pressure change of the liquid in the piping of the hydraulic cylinder are calculated based on the pressure in the hydraulic cylinder detected by the pressure sensor, and the volume change of the liquid is calculated. 1. A roll shift device comprising a control device configured to appropriately position the roll in the axial direction in consideration of the amount of the roll.
